T450s Intel 5500 Graphics no 4k 60HZ

2015-07-30, 21:29 PM
Hi Guys, i bought myself an Eizo EV3237-BK 4K Monitor for my T450s. Since i got it i was not able to run it at 4k 60hz. it is stuck at 16 bit and 30 HZ. According to the Technical Specs of the System it promised 4K 60 HZ. Im on the latest bios and Drivers with no energy saving plan activated. Anyone has the same issues? i would like to hear from an Lenovo Official about this issue! Best, Marc

Are you on BIOS 1.16? Have you activated IGD Core Display Clock as 675MHz in BIOS?

Hi Colonel,

I was able to upgrade the bios to 1.16 on Windows 10 with the Windows 8.1 bios update utility.

Where would that setting be in the BIOS? I can't find it and I'm already at BIOS 1.20 which is currently the latest. My 4K still isn't working on Linux, but I did get it working (really buggedly) on Windows for a while...
